Manchester United defender Nemanja Vidic has welcomed the club's new signings.
"My aim every season is always to improve. It's important that I show people I am a consistent player - that's why I must keep improving. I want to play better and help the team win trophies. I don't think about just me, I think about everyone. It is not just about playing well for yourself, you need to play as a team. We did that last year and we need to do that again."
